It's not that easy really. Several European countries have FISA s.702 functional equivalents that enable intelligence to get orders for interception of personal information on servers and entities within their legal jurisdiction. (e.g., The French Law on Intelligence and the German BND Act)
It's easy to say that the US should just scrap s.702, but unless it's reciprocal with Europe scrapping their interception powers as well, that's a pretty unrealistic ask.
